    Aren't quite a few folks set up to filter and use cooking oil in their diesel engines? I think that you have to start the engine with regular diesel, but after that, your exhaust smells like the fry station at the local McDonald's.

    True but this claims to be better.

    Among those is cooking oil, which currently needs to be cleaned thoroughly in an energy-intensive process to rid if of its contaminants before it can be turned into biodiesel. The approaches in use today can only handle feedstocks with 1-2 percent contaminants, whereas the durable new process developed by the RMIT team can handle feedstocks containing up to 50 percent contaminants.

    Economically speaking, can this compete pricewise with pumped-out-of-the-ground diesel?

    Well diesel is not pumped out of the ground crude oil is.

    It depends on the political situation, biodiesel might get a tax advantage for being carbon neutral.

    You know what I mean. Crude has a lot of advantages--source for gasoline and asphalt as well as diesel.

    I suspect the amount of used cooking oil is quite limited in comparison to crude oil production.
